Termux is notable is because you in fact don't need a virtual machine at all, or even a proper container. Even the "chroot" aspect is basically just to create a facade to make software work with less effort; it's not literally needed. And you can indeed run typical graphical Linux software as long as you have a compatible display server; Termux offers an X server as an add-on.
This doesn't mean that Android is the same as desktop Linux, but that's not the point here. The point is that Android runs the Linux kernel, and not just in name only. You actually can make use of the Linux aspect of Android, which many of us do.
It's possible that Google will lock down Android further in the future and make the host Linux environment less usable for stock Linux apps, but today you can run quite a lot of typical CLI and even desktop Linux software directly in Android with minimal fuss. Even if it's a little cumbersome, it's quite useful in a pinch.
I'd argue whether you can readily install software to the Linux host environment is also neither here nor there. For an immutable abroot setup like SteamOS, you can't really install directly to the host environment, but in my mind that does not make it any less "desktop Linux" or Linux kernel based.
